According to a report released today, Ludwig Dairy in Dixon, Illinois, is recalling all products – including cheese and milk – sold in Cook County and several other counties due to problems with the pasteurizing equipment.

The dairy company explained that controlled pump that is supposed to stop the production of raw milk if there are problems was bypassed and replaced with a pump that did not do the same. Therefore, raw milk may have been mixed with pasteurized milk. Raw milk and cheeses, ice cream, and other dairy products made with raw milk can be contaminated with bacteria including Brucella, Campylobacter, Listeria, Mycobacterium bovis, Salmonella, Shiga toxin-producing E. coli, Shigella, Staphylococcus aureus, Streptococcus pyogenes, and Yersinia enterocolitica.

Although no illnesses have been reported, Ludwig is taking its products off store shelves in Cook, DuPage, Kane, Lake, McHenry and Will counties in Illinois as a precautionary measure. In addition, the company reports that dairy items distributed in Indiana, New Jersey and New York have also been recalled.
